CHARLES F. SPENCER, OF ROCHESTER, NEW YORK.

Letters Patent No. 73,663, dated January 21, 1868.

IMPROVEMENT IN LAMPS on snow tttttnt t: in these g itters Ejntmtzmtmuting that at flgt smut.

TO ALL WHOM 1'1 MAY CONCERN:

Be it known that I, Cunnnus F. SPENCER, of Rochester, in the county ofMonroe, and State of New York, have invented a certain new and usefulImprovement in Lamps; and I do hereby declare that the following is afull and exact description thereof, reference being bad to theaccompanying drawings, making part of this specification.

Figure 1 is an elevation of the upper portion of a lamp, showing myimprovement.

Figure 2, a similar view in section.

Figure 3, an elevation, showing the soverhlparts separated.

Like letters of reference indicate corresponding parts in all thefigures.

My improved lamp is on a plan similar to that patented to M. H. Collins,September 19, 1865, No. 49,984. The invention consists in soconstructing and arranging the parts, that the chimney is brought downor located in close contact with the top of the lamp-body, covering orenclosing the spur-wheel or wheels for raising the wick, by which meansthe oil is more easily raised for supplying the flame, and the parts arein more compact form. It also consists in imparting motion to thespur-wheel or wheels. by means of a gear, forming part of a. revolvingcap, resting on the collar of the lamp-body, said cap also serving tohold the chimney, which is thus simply turned to elevate or depress thewick.

In the drawings, A indicates the lamp, and B its collar. On the collarrests, and turns accurately, acap, 0. This cap has a broad flange, a,for supporting the chimney D, and a gear, b, at the top, in which meshesa, pinion, 0, attached at the end of the ordinary shaft (2, of thespur-wheels f, which raise the wick. The cap has also numerousperforations, gg, at the bottom, for admitting air.

By this means, it will be seen that the chimney D is brought clown or,located closely over the top of the lamp-body, enclosing the spur-wheelshaft cl, thereby bringing the top of the wick so much the nearer thebody of oil. Heretofore, this could not be effected, on account of theprojection of the shaft, which limited the position of the base of thechimneyabove said shaft. I

By thus providing a means for operating the Wick, as above described, Iam enabled to avoid this projection of the shaft, and locate the chimneyand wick-tube lower, and, consequently, draw the oil more effectively tothe wick, and also place the-whole in a. more compact form.

The cap 0 serving both to sustain the chimney and to give motion to thespur-shaft, not only brings the chimney lower, but also forms anarrangement for adjusting the wick, much simpler and more effective thanthe ordinary projecting spur-shaft, besides being much more elegant inform, by enclosing and hiding the parts.

By this arrangement, I avoid the main objection to this class ofburners, by depressing the chimney and gearing the parts to move fromit.

What I claim as my invention, and desire to secure by Letters Patent, is

1. So arranging and combining the parts of'the burner, that the chimneyis located below the lcvel of the spur-wheel shaft, and in close contactwith the lamp-body, and made to enclose the said' shaft, as herein setforth.

2. I also claim the combination, with the chimney, of any suitable gearthat will impart motion to the wick by simply turning the chimney, asherein set forth.

3. I also claim the arrangement of the revolving cap 0, serving both asthe support for the chimney and as the gear for actuating the wick, asherein set forth.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
